I just grabbed a 1080 and it's pretty slick. Honestly I think that VR has really rekindled the video card wars - and that's good for us as consumers. I wouldn't recommend NVidia over AMD right now, though - I went with NVidia because it is the devil I know. I'm used to the company's quirks and didn't want to jump to a whole new batch of problems - because every tech company has their own set of issues. =)

I have an EVGA GTX 970 and with the Oculus Rift it does a wonderful job!

I don't actually know about the SLI/Crossfire, but I see a lot of "VR-ready" PCs and Laptops offered by a lot of companies and they use to install the video card in SLI/Crossfire so it may work, maybe not needed but Works.

My AMD setup works just fine when I installed Crimson (AMD's Radeon software) and did a fresh install of Win10. At this point, sticking with the devil you know is not a bad option.

I just got a GTX 1080 and it is awesome. I will say though, I've already bumped up against the card's limitations by putting all graphics settings on ultra for a few games. Super sampling is another way to quickly utilize your new gpu to it's limits. I think one argument for Nvidia at the moment is that their cards use less power than similar AMD cards, so you can over clock them without hitting thermal limits. VR gives you legitimate reasons to want to over clock any card you buy (the experience with higher graphic settings is way better), so that's one thing you may want to consider.

For my development rig, I'm using an R9 380 for AMD and an ATI 1070. The 1070 is about 50% more powerful, but I've found (as a developer) my games play about the same speed regardless. I'm suspecting with current gen game engines the bottleneck is mostly related to single tasking and CPU thresholds... hoping to test more engines over the next few months though.

We are getting interesting & unique bug reports by 1080 users.

I suspected this! Most games when supersampled don't scale well. SportsBar VR being one of the exceptions.

Have you guys tried the Deus Ex Mankind VR experience? There's lots of graphic settings to fiddle with

I have not gotten into the Deus Ex series. Have you played Deus Ex Mankind VR? Interesting to know that some graphic settings needs to be made for it. What type of graphic setting tweaks you need to perform?

I'm using a reference GTX 1080, but if you're looking to get a new card still, I'd personally stay away from reference cards if possible. The 1080 is also a beast of a card, and while it helps with supersampling and some more demanding tasks, it's honestly a little overkill for VR in its current form. Other NVIDIA Pascal cards, like the 1070 and 1060, are great cards to get started with desktop VR.
